Not quite sure i would agree with some of the recommendation's in that thread, the idle/low throttle side of the PCV system (the one with the one way valve)can be junked in most cases when going FI, as all it does is to draw a lot of oil vapor into the plenum (due to the very high vacuum generated at idle/low throttle) and pool oil in the low points of the plenum and then burn it on the first large throttle opening, not good on FI as it can lead to a sudden lowering of fuel octane due to excess hydrocarbons from the burnt oil, which can result in det.
The same happens with the N/A but its a somewhat lesser lesser risk as there is no boost pressure to add to the equation, so less chance of det, but still not desirable, which is why most people go for fitting a sealed catch can to this side of the PCV system to help eliminate the oil.
Its still desirable/beneficial to utelise the PCV system as it helps with ring/bore seal and to a smaller existent with stopping oil seal weep because its causes a slight vacuum in the crankcase,
The other side of the PCV system is the high load/full throttle side which is much more effective in helping with ring/bore seal etc when going FI as rather than as suggested be allowed to be vented to atmospheric air, it should be plumbed back into the turbo/supercharger intake which provides a good vacuum effect, obviously via a catch can to prevent extra oil contamination.
